Response of hybrid maize (Zea mays L.) to precision water and nutrient management through drip system


Author(s): Richa Khanna and T Sheshadri

Abstract: To study the synergistic effect of water and nutrients applied precisely through drip fertigation a study was conducted at UAS, Bangalore in Kharif season of 2012. The experimental results indicated that maize crop responded very well to precised application of nutrients and water. The observations taken on growth parameters indicated that treatments provided with drip fertigation with 125 per cent RDF through water soluble fertilizers recorded maximum plant height at harvest, highest leaf index at 90 days after sowing and maximum dry matter accumulation in cobs and in total plant at harvest. A reduction in fertilizer dose to 75 per cent of RDF through water soluble fertilizers resulted in statistically comparable values of above mentioned characters as that of 125 per cent RDF. This clearly indicates the benefits of precision farming in resource savings. The yield data also revealed that though maximum yield was obtained with drip fertigation with 125 per cent RDF through water soluble fertilizers, but it was statistically at par with drip fertigation with 100 per cent RDF through water soluble fertilizers. Further, the later was again found to be at par with drip fertigation with 75 per cent RDF through water soluble fertilizers.
